Catholics who believe the literal interpretation of John 6 face a serious dilemma. Both the “eating and drinking” and “believing in Jesus” produce the same result—eternal life. What if a person “believes” but does not “eat or drink?” Or what if a person “eats and drinks” but does not “believe?” Does this person have eternal life because he met one of the requirements but not the other? . . . God forbids anyone from consuming the blood of a sacrifice. If Jesus were teaching the multitudes to literally drink His blood, He would be teaching them to disobey God.
